Description

edit

The gall is an elongate swelling that tapers into the young shoot. It is 10 millimetres (0.39 in) to 15 millimetres (0.59 in) long by approximately 5 millimetres (0.20 in) wide. The bark around the gall is smooth and contains one larva which has three dorsal annulets on the third abdominal segment, and a suranal plate without pseudocerci.[1][2] Pupation is probably in the gall.[1]

In Britain the gall has been found on eared willow (Salix aurita).[2] Elsewhere it has also been found on grey willow (S. cinerea), downy willow (S. lapponum) and (S. starkeana).[1]

Other similar looking galls in the Euura atra subgroup are,[3]
